src/sys/netsmb [netbsd-5]: smb_smb.c
Pull up following revision(s) (requested by tron in ticket #1104):
sys/netsmb/smb_smb.c: revision 1.31
sys/netsmb/smb_smb.c: revision 1.32
Fix detection of SMB capabilities according to the CIFS spec:
1.) SMB_CAP_LARGE_FILES advertises support for 64-bit file offsets.
2.) SMB_CAP_LARGE_READX and SMB_CAP_LARGE_WRITEX advertise support for
large reads and writes (larger than 64KB).
The code previously only used SMB_CAP_LARGE_READX and SMB_CAP_LARGE_WRITEX
which is not correct and doesn't work for the Apple Time Capsule which
only supports SMB_CAP_LARGE_FILES. With these changes SMBFS can copy a
5GB to a Time Capsule and read it back without problems.
Thanks a lot to Allen Briggs for pointing out the broke assumptions
and explaining the CIFS spec to me. This fixes PR kern/42175.
Fix cut & paste error spotted by Nicolas Joly.
